The sum of two numbers is 60 and their quotient is 4. What are the two numbers?

Answer 1

Let x = larger number

Let y = smaller number

eq.1: x + y = 60

eq.2: x/y = 4

Solving eq.1 and substituting into eq.2, we have...

y = 60 - x

x/60-x = 4

x = 240-4x

5x = 240

x = 48

y = 60-48 = 12

Check:

48 + 12 = 60

48/12 = 4
